Actually there seems to be a problem with this function, 

I am german, and certainly the locale-Pack for de_DE,utf-8 is installed and i 
can use it for other things like printing dates in the correct language 
(month-names). But in case of ctype_alpha I get always the answer FALSE if 
testing a word containing one of the typical german letters ä,ö,ü,ß (and 
their capital counterparts) ..

This is not a bug in PHP as PHP uses the OS functions to determine wheather 
something is an alpha character or not. Also, this has nothing to do with 
character sets at all, it's just the locale that matters. Do you actually have 
the et_EE locale installed? Anyway, this is not a bug in PHP.

Description:
------------
ctype_alpha fails to identify at least two iso-8859-15 characters: s-caron (š) 
and z-caron (ž) and their upper-case equivalents.

Reproduce code:
---------------
<?php
setlocale(LC_ALL,'et_EE');
header("Content-Type: text/html; charset=iso-8859-15;");
$strings = array('äöäaa','sete','ašew', 'aže','üõüä','teŠt','Žombie');
foreach ($strings as $testcase) {
        if (ctype_alpha($testcase)) {
                echo "Alpha test - $testcase - PASSED.<br />\n";
        } else {
                echo "Alpha test - $testcase - FAILED.<br />\n";
        }
}
?>

Expected result:
----------------
Alpha test - äöäaa - PASSED.
Alpha test - sete - PASSED.
Alpha test - ašew - PASSED.
Alpha test - aže - PASSED.
Alpha test - üõüä - PASSED.
Alpha test - teŠt - PASSED.
Alpha test - Žombie - PASSED.

Actual result:
--------------
Alpha test - äöäaa - PASSED.
Alpha test - sete - PASSED.
Alpha test - ašew - FAILED.
Alpha test - aže - FAILED.
Alpha test - üõüä - PASSED.
Alpha test - teŠt - FAILED.
Alpha test - Žombie - FAILED.
